With 13 reservoirs and 3 controlled lakes in the 400-square-mile East-of-Hudson (EOH) New York City watershed, many watershed residents, understandably, are unfamiliar with the physical characteristics, water quality issues, and overlapping municipal boundaries of each reservoir basin or subwatershed. The reference material provided under "Related Info" to the right is intended to provide such information at a glance, to allow stakeholders to assess the water quality impacts of proposed development projects and zoning amendments in their districts, and to provide contact information for local and regional environmental groups that can offer guidance and assistance with citizen complaints and concerns about the management of their watershed.
